THERAPEUTIC APPLICATOR.

Specification of Letters latent.

Application filed January 13, 1916. Serial No. 71,915.

To all whom it may concern.-

Be it known that 1, CHARLES H. VIoL, a citizen of the United States, and a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Therapeutic Applicators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in-the art to which it a pertains to make and use the same.

T his'invention relates to improvements in apparatus for the treatment of diseases and more particularly to an improved applicator for the therapeutic application of radium.

Heretofore, it has been proposed, in the construction of means for applying radium to affected parts of the human body, to incorporate a salt of radium into organic varnish,but it has been found in ractice that such varnish will deteriorate un er the effect or influence of radium rays from the radioactive materials employed. Such applicators have been unsatisfactory due to their short life.

The object of my invention is to provide an applicator for the therapeutic application of radium, which shall avoid the defects above alluded to and which shall retain the radioactive material in a uniformly spread condition without liability or even possibility of the retainin or holding medium becoming deteriorate or weakened in any respect.

With this and other objects in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings: Figure'l is a perspective .view of an applicator embodying my invention, and Fig. 2 is a sectional view of the same.

In constructing my improved applicator, I incorporate radioactive material 1nto glass .or similar silicious, glassy or glaze substance, and thoroughly distribute said radioactive substance into the glass or similar ment 4 to *active surface of substantial substance while the latter is in a molten state.

While any of the well-known radio-active substances may be employed, I prefer to incorporate with the glass or similar substance, a radium compound, viz. a salt of radium, such ass radium chlorid, radium bromid, radium sulfate, soluble or insoluble salts of radium.

The glass .or similar material 1,'having the radium salt 2 incorporated therein, is fused in a thin sheet or film on a suitable base 3, which latter is preferably of metal.

The base 3 may be made circular in form or it may have any other desired shape and it may be provided with a threaded enlargefacilitate its attachment to any suitable carrier, holder or handle.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is

1. A therapeutlc applicator for local application, comprising a non-porous vitreous substance having radioactive salt incor rated therein and fused, to provide a ra 'ouniform radiointensity. v i

2. A therapeutic applicator comprising a base, a vitreous substance having radioactive salt incorporated therein and. fused in a layer to said base to provide an applicator for local a plication of radioactive rays of substantial y uniform intensity throughout the area thereof.

3. A therapeutic applicator comprising a base, a vitreous substance having a salt of radium incorporated therein and fused in a layer to said base to provide for local application of radioactive rays of substantially uniform intensity throughout the area thereof.

In-testimony whereof, I have signed this specification in the presence of two subscribing witnesses. I I CHARLES H. VIQL.

or in fact any of the an applicator Patented Jan. 2, 1917.
